    asm (".pushsection .test\n"
         ".long 0, %P0, %P1\n"

         ".popsection"
         :: "i"(ENUM_VAL2), "i"(2));

but this is quite hackish, %P isn't meant for this.  On newer GCC
versions there is %p, which is better.

Thanks - it is what exactly I wanted.


I knew I forgot something :-)  Please use "%c0" instead, which works
on every GCC version, and is portable even.
